EDWIN WESSIVLAN, OF QUINCY, MASSACHUSETTS.

PORTABLE CAMP-STOVE.

Specification of Letters Patent.

Patented Apr. 4, 1916.

Application filed July 26, 1915. Serial No. 41,934.

To all whom it may concern Be it known that I, EDWIN WESSMAN, a citizenof the United States, residing at Quincy, in the county of Norfolk andState of Massachusetts, have invented new and useful Improvements inPortable Camp- Stoves, of which the following is a specification.

The invention relates to a stove, and more particularly to the class ofportable camp stoves.

The primary object of the invention is the provision of a stove of thischaracter wherein Wood alcohol can be used as a fuel for cookingpurposes, the stove and fuel reservoir being novel in construction so asto assure perfect combustion at the burnerand the proper feed of thefuel thereto.

Another object of the invention is the pro vision of a stove of thischaracter wherein the fuel can be fed under pressure to the burner, thesaid stove being readily portable so that it may be conveniently carriedfrom place to place, and thereby making it handy for camping purposes.

A further object of the invention is the provision of a stove of thischaracter which is simple in construction, thoroughly reliable andefiicient in use, strong, durable, and inexpensive in manufacture.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawings,and pointed out in the claim hereunto appended.

In the drawings :Figure 1 is a side elevation of a stove constructed inaccordance with the invention. Fig. 2 is a vertical longitudinalsectional view through the burner. Fig. 3 is a vertical longitudinalsectional view through the reservoir for the fuel. Fig. 4 is a top planview thereof. Fig. 5 is a top plan view of the burner. Fig. 6 is asectional view on the line 66 of Fig. 3.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail. the stove comprises a reservoir 10,preferably in the form of a tank open at its upper end, and has fittedtherein a pressure piston 11 provided at its periphery with a groove 12in which is seated a tension ring 13 working against packing ring 14concentrically disposed relative thereto, while fixed to the piston 11and overlying the rings 13 and 14:. is an annulus or flange ring 15which is bolted or otherwise secured to the said piston and retains thetension and packing rings 13 and 14 in the groove 12 therein. Adjustablythreaded in the piston 11 are tension screws 16 which act upon thetension ring 13 for regulating the same.

Bridging the upper open end of the reservoir 10 is a cross strap 17formed with hook terminals 18 for detachable engagement withdiametrically opposed lugs 19 formed on and projecting laterally fromthe body of the reservoir 10, and passed through the strap 17 centrallythereof is a lift stem or rod 20 which is detachably engaged centrallyin the piston 11 and has formed on its outer end a knob 21 so that thepiston 11 can be raised within the reservoir 10 after the loweringthereof in a manner presently described.

At opposite sides of the lift stem 20 and adjustably threaded in thecross strap 17 are adjusting stems 22 provided at their outer ends withknobs 23, while at theirinner ends are formed heads 24 against whichwork coiled expansion springs 25, the

same working against the piston 11 for moving the same downwardly withinthe reservoir or tank to exert pressure upon the body of liquid fuelcontained therein, it being seen that upon adjustment of the stems 22the tension of the springs 25 can be varied, thereby regulating thepressure exerted by the piston working within the reservoir. Tapped inthe reservoir at its bottom is an outlet nipple 26 to which is connecteda feed tube 27, the same being also connected to a burner stem 28integral and communicating with the crossed burner tubes 29 which arefitted at their outer free ends with removable plugs 30 to permit thecleaning thereof. the tubes being formed with orifices 31. as usual forthe ignition of the fuel for the issuance of the flames from the burner.The burner stem 28 is passed centrally through the bottom of asubstantially hopper or dishshaped burner pan or casing 32 supportedupon legs 33 and having mounted thereon a circular rim 34 containing arest spider 35 on which is adapted to be placed the cooking utensils sothat the same will be disposed in the path of the flame or flames fromthe burner.

The outlet nipple 26 tapped in. the reservoir 10 is provided with apressure gage 36 so that the pressure within the reservoir can bedetermined when inspecting the gage.

It will be apparent that When the cross strap 17 is detached from thelugs 19 the piston 11 with the stems 20 and 22 can be removed from thereservoir 10 for the convenient filling of the same with liquid fuel,preferably wood alcohol, which is adapted to be delivered to the burnerunder pressure.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and manner of operation of thedevice will be clearly understood, and therefore a more extendedexplanation has been omitted.

WVhat is claimed is The combination with-a burner, of a cylinder havinga valved communication with the burner, diametrically opposed lips onthe cylinder, a bridge-piece lnving a hook end detachably engaging thelips, said bridgepiece having threaded and non-threaded apertures,screws engaged in the threaded apertures, a sliding stem working in thenon-threaded apertures, a piston Within the cylinder and detachablyconnected with the sliding stem, and compression springs resting uponthe piston and acted upon by the screws.

In testimony whereof I aiiix my signature in presence of two witnesses.
